48h before entering Belgium, it is mandatory to fill in a Passenger Locator Form (unless the stay is under 48h). The form can be found on https://travel.info-coronavirus.be/public-health-passenger-locator-form.
Based on infection rate, Belgium lists countries by color codes: green (travel allowed), orange (vigilance needed) and red (travel strongly discouraged).
From 13 November, Belgium has listed Estonia as a “red zone” country. This means that passengers coming to Belgium from Estonia will likely have to stay in quarantine and get tested. Belgian authorities strongly discourage travel to Estonia.
Until further notice, travelers returning from a red zone will not be under the obligation to be tested, except in the case of obvious symptoms. However, depending on their answers to the self-assessment questionnaire attached to the Passenger Locator Form, a passenger may receive a sms with instructions to stay in 7-day quarantine and to get tested on the 7th day of quarantine. It is mandatory to follow these instructions. Test results will come in 1-2 days. Therefore, all passengers from Estonia to Belgium should take into account 7 + 2 day quarantine (in case the result is negative). If the result of covid test is positive, it is obligatory to remain in quarantine for another 7 days, even if no symptoms occur.
If symptoms appear coming from abroad, the person must go into self-isolation and be tested as soon as possible. If the result is positive, it is mandatory to stay in quarantine for 7 days. If after 7 days symptoms have not disappeared, then quarantine must be extended for another 7 days.
From 23 November it is possible to do Covid-19 test without a prior visit to the GP. Test centers in Brussels are marked on the interactive map.
Please see comprehensive information about entering Belgium on the website of SPF Foreign Affairs.
